Demineralization with ion Exchange is the proccess
of removal of the ions in the water. The positive
value ions are exchanged by strong acid cation resin
and replaced by Hydrogen ions. The negative value
ions are exchanged by strong basic inion resin and
replaced by hydroxyl ions. By this proccess H2O
produced and the conductivity of raw water is decreased.
When conductivity and silica have to be reduced
to very low levels, mixed bed and electrodeionization
(EDI) systems are applied.
As the proccess includes many steps during regeneration,
our company install PLC controlled Ion Exchange
Plants unless the customer insist on manual operated
ECOEDI from Tolem is an electrodeionization
(EDI) technology. Its continuous, chemical-free
operation and proven, modular design offer substantial
benefits over conventional mixed-bed for water processing
applications in the power generation, pharmaceutical,
semiconductor, biotechnology and other industries.
Conventional water treatment systems relied on chemical-based
deionization to remove dissolved solids, but at
a high cost. The resin beds that the water passes
through must be regenerated frequently using a batch
Regeneration chemicals are not only costly, they
pose a toxic hazard to the workplace and the environment,
demanding rigorous safety protocols. As a result,
chemical-based deionization is complex and expensive
With ECOEDI technology, industry now has a chemical-free
alternative that is safer for the environment, is
simpler to operate and maintain, and costs less.
